Demostramos que existe una población de TNOs, de la cual 2003 EL61 es el objeto de mayor tamaño, que se mueven en órbitas muy similares y cuyas superficies...
A possible explanation has been discovered for the UV peak at 2175A based on the presence of fullerenes and buckyonians in interstellar matter. This is a...
Post-common envelope binaries as the precursors of extremely red old stars
Modelling dust formation in single stars evolving through the carbon-star stage of the asymptotic giant branch (AGB) (i.e., the late evolutionary stages of Sun...
Powerful winds driven by a supermassive black hole
The supermassive black holes in the centres of galaxies have a basic influence on their evolution. This happens during a phase in which the black hole is...
Proton acceleration in thermonuclear nova explosions revealed by gamma rays
Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf. Accumulation of hydrogen in a layer...
Radial variations in the stellar initial mass function of early-type galaxies.
The hypothesis of a universal initial mass function (IMF) - motivated by observations in nearby stellar systems - has been recently challenged by the discovery...
Rapid Orbital Decay in the 12.75-minute Binary White Dwarf J0651+2844.
We report the detection of orbital decay in the 12.75-minute, detached binary white dwarf (WD) SDSS J065133.338+284423.37 (hereafter J0651). Our photometric...
Rapid quasi-periodic oscillations in a relativistic jet
Active galactic nuclei (AGN) consist of a supermassive black hole fed by the circumnuclear material close to the galaxy center. Around 10% of the AGNs develop a...
The “Lambda Cold Dark Matter” (CDM) cosmological model is the current theory credited for reproducing the physics responsible for the formation and evolution of...
